Application tiled April 6,1912. Serial No. 688,831.

My invention relates to an improvemenz an j in bracelets of thatv type usually known referred to as expansion/l bracelets, .and lada ted, if desired, to carry, a watch.

ore particularly,

v to an improvement upon Ythe bracelet for shown in Fim 2; Fig.

which l filed application or Letters Patent. on the seventeenth day of January, S1912, Serial Number 671,714, and allowed on the liiz'th day of March, 1912, the object being to so construct the bracelet that the use of lugs formed on one of the units or links -or the purpose of guiding the one link in its movements upon the other will be avoided, and the entire surface or surfaces of the several units be perfectl smooth and without projections or protu erances of any kind.

A further object of the invention is to materially lstrengthen the bracelet referred to in the application for patent, supra, and to more perfectly guide the several links in their movements with relation to each other, and with these and other ends in View consists in certain novel features o construction and combinations of parts as will beV hereinafter more fully described and pointed outin the claims.

ln the 4accompanying drawings, Figure 1 is u side view of my improved braceletv partly in elcvationand .partly in section, the several links being'in their normal or closed positions; Fig. 2 is an enlarged vertical sectional view oi several of the links in their expanded adjustment; 3 is an en. hirged horizontal sectional view of the links 4 is a sectional ,View

taken on the ine 4-'-4=, 0f Fig. 1. Fig. '5 is a detached view in perspective of one of the 6 is a detached perspective View ot' a partially formed inner link.

'Referring to the drawings it will be seen that each of the outer and inner links is outer links; Fig.v

made of a box-like orm,`and so assembled'I that the exterior surfaces'will be plain or smooth and Without projections of' any kind.

Each of 'the outer inks, as: illustrated in Fig. 5, is preferably, formed of a single -piece4 1 of` metalfand' tonipr'ises the outer widerv plate the invention relates lper extreme edges 19 of the and 15 of the-inner link, the narrower plate l-11 of the outer link tting between the edges 20e-20ct the lates 11iA and 15 of the inner en the inner and vouter links of one link will having smooth surfaces.

:spring being y -and inner links in their normal or closed adjustment, as illustrated in Fig. 1, but erland the inner narrower plate 11, the two plates beine connected by the end plates lf2-12, each o? the end plates being' provided with a hole or'opening 1.3, said end plates being of a widthv equal to the width of the narrower inner 'plate 11.

The inner link illustrated in Fig. 6 coinrises Afour-Walls or plates'preferably made rom a single piece of metal .und bent to form thesicle plates 1-1-15 and the end 'after the sprin has been properly assembled therewith as lerenafter' described, being bent up and soldered vto the end of the side plate 14 to form the end plate or Wall 17.

l Vv'hile I liaveil'lustratedand described the outer and mner'lmks u s each being made from a singlefpiece of metal, it will ot course be understoodthat each may be made up of several piecesor parts soldered or otherwise securedtogether. y

In the inner link iscontaii'ieda rod 18 tightly secured at one end to the end plate 16, and extending longitudinally the' length of the the end plate 17 .V On this rod 18 is mounted one end 12 of the outer link, the rod passing throughthe opening ,1d therein, the edges of -thc'outer plate 10 ofthe outer link 'overlyingI and-resting and moving upon the up- -sidevplates 1l link?, so that-w are assembled, the several edges of the walls terminate flush with the sur linkto or Within-'a short distance ci",l

`v.Wall 16, theelongated end ott-the side 15,

faces or sides of the other link, all as illus' I trated insection inFig. 4,'thereby-producing a 4bracelet 9i vassembled units or links Around the ro'dlS is a coiled Wire spring 21 one end thereo'l?` impinfring against the en inner 'linkand the o or bearing againstt outer link, the tendency, therefore, ofthe to hold the respective outer mitting the links'to slide one. upon the' ot ier, and o ened or pantially separated, or expende as illustrated in Figs. -2 and 3.

In ,the` movement or travel of the links,

one ,upon the other, it .will be seen thattheyl 'are'guided by. means of the-rod 18'r'igid1-y secured 'to the inner link and .passing plae 17 of' the posite' en impingin e e'iidfplate 12 of thfA 'iid Ving inserted in bled 'with 'the partiallyformed-inner link illustrated in Fig. 6, the rod or bar 18 bey the opening 13 in the end plate v12,; after the rod or'bar 18 has been inserted into the outer link a sufficient distance, the'coiled spring 21 is then passed over the inserted end thereof and the plate 17 bent upwardly and soldered or otherwise secured to the plate 14 whereby to complete the formation 'of the inner link and the sembling thereof .with the outer link.A

What I claim is 1. An expansible bracelet comprising assembled outer'and inner links, each of thel outer links comprising an outer and inner' plate and perforated end plates, and each of the inner links comprising two side plates-connected by end plates, said side plates fitting across the opening between the outer and inner plates of said outer link; a guide bar rigidly secured to one end plate of the inner link, and extendiw through the opening in one of the end plates of the and to #Nithin a short distance of end plate of the inner link, and a outer link the other spring I,coiled around said guide bar and having one end implnglng against one end plate of the inner link and the other against one end plate of the outer link,`substantially as described. l

2. An expansible bracelet comprising ass sembled outer and inner links, each outer link comprising a'n outer plate and an inner plate of less width than the outer plate, said inner and outer plates being connected by perforated end plates of a width substantially equal to that of the inner plate,` and each of the inner links comprising two side plates of a Width to extend across .the open- Copies of .this patent may be obtained for ive cents each, lby Washington, 2D.l C.

a spring coiled around end ing between the outer and inner plates of saidouter link, said side plates being c0n the outer link and to within ashort distance ofthe other end plate of theinner link, 'and said guide bar and having one lof its ends impinging against an plate of the outer link and the other end against an 'end plate of the. inner link, substantially as described;

3. An eXpansible bracelet comprising assembled outer and inner links, each outer link comprising an outer plate and an iny ner plate of less width than the outer plate, said inner and outer plates being 'connected by perforated end plates of a width sub- -stantially equal to that of said inner plate,

each of the inner links comprising two side plates of a width to tit across thebpening between the; outer and inner plates of the' outer link, said side plates fitting below the and over the4 outer plate of said outer link edges of the inner plate of said outer link, said side plates of the inner link'being connected by end plates, a guide bar one end of which is secured to an end plate `of the inner link and extending to within a short distance of the other end plat-erof said inner link, said guide bar passingv through one perforated endplate ofthe outer link, and a spring coiled around said guide bar, oneend thereof impinging against the end plate of the outer link, and the othel end against the end plate of the inner link, substantially as described.
